Brondell vs Apex Countertop Filter Comparison: Which One Is Better?

Both Brondell and Apex make popular countertop water filters, but they target different needs. Brondell focuses on sleek design and easy installation with a diverter valve, while Apex emphasizes high capacity and heavy-duty filtration for sediment-prone water. If you want a compact unit that switches between filtered and unfiltered water effortlessly, go with Brondell. For maximum filter life and contaminant reduction on a budget, Apex is the better choice.

Quick Answer

Brondell and Apex countertop filters differ in filtration technology, flow rate, filter lifespan, and installation method. Brondell uses a carbon block filter with a quick-connect diverter, while Apex uses a larger carbon block with KDF media. Brondell filters about 200 gallons per cartridge; Apex filters up to 500 gallons. Both reduce chlorine, taste, and odor, but Apex also handles sediment and heavy metals better.

Filtration Media: Brondell uses a coconut shell carbon block; Apex uses a carbon block with KDF-55 and sediment filter layers.
Flow Rate: Brondell flows at about 1.0 gallons per minute; Apex flows at about 0.5 gallons per minute due to more restrictive media.
Filter Lifespan: Brondell cartridges last 200 gallons (about 2 months for a family of 4); Apex cartridges last 500 gallons (about 6 months).
Installation: Brondell uses a diverter valve that screws onto the aerator threads; Apex uses a hose adapter that connects to the faucet spout.

Filtration Performance: What Each Removes

Brondell’s countertop filters (like the Coral series) use a single-stage carbon block that reduces chlorine, taste, odor, and some cysts. It does not have a sediment pre-filter, so if your water has visible particles, the carbon block can clog faster. Apex’s countertop filters (such as the MR-1050) incorporate a layered design: a sediment wrap, carbon block, and KDF-55 media. This combination reduces chlorine, lead, mercury, and sediment, and it also inhibits bacterial growth in the filter.

For common tap water contaminants, both filters are effective against chlorine (over 95% reduction) and bad taste. However, Apex achieves higher reduction for heavy metals like lead (up to 99%) and also reduces iron and manganese. Brondell does not claim heavy metal reduction beyond what a standard carbon block can do. If your water has high sediment or heavy metals, Apex is the more robust choice.

Installation and Ease of Use

Brondell filters are designed for renter-friendly installation. The diverter valve screws directly onto your faucet’s threaded aerator (if you have a standard male thread). You then connect the filter hose to the diverter, and a lever switches between filtered and unfiltered water. No tools are needed, and the filter sits on the counter.

Apex filters require a bit more effort. They come with a plastic hose adapter that screws onto the faucet spout (some faucets need an additional O-ring or washer). The filter unit is larger and heavier, and the hose connects via a push-fit fitting. Switching between filtered and unfiltered is done by turning a knob on the filter head. Some users report that the adapter can leak if not tightened properly, and the filter may need occasional burping to release trapped air.

Flow Rate and Water Waste

Brondell filters have a relatively high flow rate of about 1 gallon per minute, which is close to normal tap flow. This makes filling a pot or glass quick. However, because the filter is small, the flow rate can drop noticeably as the cartridge nears the end of its life.

Apex filters have a slower flow rate, around 0.5 gallons per minute, because the water passes through multiple media layers. This can be frustrating for fast filling but ensures thorough contact time for contaminant removal. Neither filter produces wastewater, unlike reverse osmosis systems, so there is no water waste. The trade-off is that the filter media will eventually saturate and need replacement.

Filter Lifespan and Replacement Cost

Brondell filter cartridges last about 200 gallons (or 2 months for a family of 4 drinking 2 liters per day). Replacement cartridges are sold individually or in packs. Apex cartridges last 500 gallons (approximately 6 months for the same usage). The longer lifespan offsets the higher upfront cost of the Apex system.

When comparing cost per gallon, Apex is generally more economical in the long run because you replace filters less often. However, Brondell’s smaller cartridges may be more convenient if you want to change filters more frequently to maintain freshness. Both brands recommend replacing the filter every 6 months regardless of gallon usage to prevent bacterial growth.

Design, Build Quality, and Space

Brondell countertop filters have a modern, compact design with a brushed stainless steel or white finish. The unit is about 10 inches tall and fits easily under most cabinets. The diverter valve is small and unobtrusive. The filter housing is plastic but feels sturdy.

Apex filters are larger and more utilitarian. The MR-1050 is about 12 inches tall and 5 inches wide, with a clear plastic housing that lets you see the sediment buildup. The hose is thicker and less flexible. Some users find the plastic feels less premium, but the transparent housing is helpful for monitoring filter condition. If you have limited counter space, Brondell’s smaller footprint is a plus.

Pro Tips

Before buying, check your faucet aerator size; Brondell works with standard male threads, but some faucets need an adapter (included).
For Apex, flush the new filter for 5 minutes before first use to remove carbon fines and air pockets.
If your water pressure is low (below 30 psi), Brondell’s flow rate may drop significantly; Apex handles low pressure better due to larger media area.
Place a small tray under the Apex filter to catch any drips from the hose connections during cartridge changes.

Common Mistakes to Avoid

Don’t overtighten the Brondell diverter valve onto the faucet; hand-tighten only to avoid cross-threading plastic threads.
Avoid using Brondell filters with well water that has high sediment; the carbon block will clog quickly and need replacement sooner.
Don’t leave the Apex filter installed if you go on vacation for more than a week; the stagnant water can promote bacterial growth.
Don’t assume both filters reduce fluoride; neither Brondell nor Apex countertop filters are designed for fluoride reduction without specialized media.

FAQ

Can I use a Brondell filter with a pull-out faucet?

Most pull-out faucets have non-standard aerator threads, so the Brondell diverter may not fit. You might need a separate adapter, but results vary. Apex’s hose adapter can sometimes clamp onto the spray head, but it’s not guaranteed.

How often should I clean the Apex filter housing?

Clean the clear housing every time you change the cartridge (every 500 gallons). Use mild soap and a soft cloth; avoid abrasives that can scratch the plastic and make it cloudy.

Does Brondell or Apex remove chloramine?

Both filters reduce chloramine to some degree, but not as effectively as chlorine. For significant chloramine reduction, look for filters with catalytic carbon. Brondell’s standard carbon block reduces chloramine by about 50-70%; Apex’s KDF/carbon blend performs similarly.

The Bottom Line

Both Brondell and Apex offer reliable countertop filtration, but your choice depends on your water quality and priorities. For a simple, fast-filtering unit with a modern look, choose Brondell. For longer filter life and better sediment/heavy metal removal, go with Apex. Measure your faucet type and test your water before buying to ensure compatibility and performance.
